I 2 Claims. (Cl. 81-163) This invention relates to a simple, compact and convenient wrench combining in one appliance thefunction of a wrench and the advantageous features of a ratchet wrench, also to provide a reversible ratchet wrench that may be a used for screwing bolts or nuts into place or unscrewing the same, and also to provide improved adjusting means for the jaws of the wrench.

A very important object of this invention is to provide means in the device so as to keep foreign matter from contacting with certain mechanism which is utilized in the operation of the socket wrench.

This application is an improvement over the application'of Albert Gauntner, Jr. for Adjustable ratchet socket wrench filed September 14th, 1927, Serial No. 219,532, patented February 4th, 1930, No. 1,746,150.

With the foregoing and other objects in view, as will hereinafter become apparent, this invention comprises the constructions, combinations and arrangements of parts, hereinafter set forth, disclosed and shown on the accompanying drawing. In this drawing,

Figure 1 is a top plan view of the invention showing but a fragmentary portion of the handle and internal gear.

Figure 2 is a section-a1 View taken on line 22 of Figure 1 showing particularly the four operative screws and the dirt protecting disk partly broken away.

Figure 3 is a sectional View taken on line 33 of Figure 1 showing especially the insertable and rotatable operating handle of the device.

Figure 4 is a detailed sectional fragmentary portion of the disk carried by the operative screw.

Figure 5 is a perspective view of the dirt protecting disk.

Referring now to the drawing, the adjustable ratchet socket wrench comprises a revolvable and pushable handle It which handle is provided with a reduced tubular portion II. This tubular portion i is slidably held in the sleeve I2 by means of an upturned collar 33 or by other suitable means and the tube 32 has a similar upturned end thereby limiting the outward pull of the handle with the relative parts. On the sleeve i2 there is a retaining ring I3 which ring holds cam collar l4 in proper relation with the end of pawls it, said pawls l5 being pivoted at pawl pivot M3 on a substantially annular shell head 25, next to and adjacent to the cam collar. In view of the fact that the pawls l5 are of conventional structure and of conventional operation it is believed that further description, operation and illustration of said pawls is not required.

' Of course the annular shell head 25 is in nonmovable relation with the handle, but this annular shell head houses a revolvable ring 24, and said ring 24 in turn is provided with suitable guide blocks H which blocks are preferably formed integral with the ring 24, so that the jaws l8 and I9 may be properly guided when the jaws are in movement in being urged away or toward each other. In order to urge the jaws I8 and I9 away or toward each other within the ring 24, four operative screws 2!) cooperate therewith as to be described hereinafter and each of said screws is provided with right and left hand threads, and set parallel to each other, as Well as in threaded engagement with the jaws I8 and. I9. The ends of these operative screws 20 furthest away from the handle I0, are set in depressions 22 and 23 of ring 24 and the opposite ends of these operative screws 20 are provided with a reduced circular portion 36 which permits the reception of openings 31 of dirt protecting disk 38 to be carried thereby. The periphery 39 of disk 38 fits within the collar 40 of internal gear 2|, the purpose of which will be set forth below. The extreme opposite ends of these operative screws 2|] are further provided with rotatable gears 29 and said rotatable gears 29 are adapted to be actuated by the meshing teeth 3|] of an internal gear 2|, which internal gear 2| is adapted to be rotated on the fixed collar 3|, which collar has a central opening and fits into the recess 21 of said gear 2|.

It will thus be seen that due to the relative location of the disk 38, it serves as a protecting member thereby preventing all foreign matter or dirt from entering around internal gear 2|, rotatable gears 29 and meshing teeth 30, thereby permitting this device to operate more efficiently and with less effort than would otherwise be obtained if this disk 38 were omitted in the construction.

It will further be seen that the internal gear may manually be rotated by the application of the thumb thereon, or it may be revolved or rotated by the insertion of square end 34 of pushable and rotatable handle into the centrally located square hole 28 of the internal gear 2|. A suitable spring 35 surrounds square end 34 so that upon release of pushing pressure, the disengagement between the square end 34 and square hole 28 is quickly accomplished.

When it is in an engaged position, the device may be used as a ratchet wrench, since ratchets 26 are suitably'provided on the outer cylindrical surface of the ring 24 that properly cooperates with pawls l5, cam collar l4, and likewise are also reversible by the provision of two pawls l5. I The'novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this fis'not to be considered limited to the exact form disclosed and that changes may be made therein within the scope of what is claimed, without departing from the, spirit of the invention.

Having thus set forth and disclosed the nature 7 of this invention, what is claimed is: 1

1. An adjustable ratchet socketwrench com I prising a shell head, a ring ratcheted in said 7 and having a plurality of internally threaded openings therethrough, the threads inonelof said jaws being right-handed and those in the other of said jaws being left-handed, a plurality of I correspondingly threaded screws passing through said oppositely threaded openings in said jaws, said screws being rotatable in said ring'atone end,'a' rotatable gear affixed to each'screw at its other end, a fixed collar projecting into said ring, an internal gear riding on said collar and '30 having its teeth in mesh with each said rotatable gear, whereby rotation of said internal gear will adjust said jaws and a disk carried by said screws adjacent to and substantially sealing the rotatable gears within the internal gear so as to pre- 35 vent foreign matter from clogging the same.

2. An adjustable ratchet socket wrench comprising a shell head, a ring ratcheted in said shell head, a pair of blocks having parallel opposed guide faces provided in said ring,1a pair of wrench V jaws disposed between said guide faces and having a plurality of internally threaded openings 5 positely threaded openings in said jaws, said 10 screws being rotatable in said ring at one end,

. a rotatable gear afiixed to each screw at its other end, a fixed collar projecting into said ring, an internal gear riding on said collar and having its teeth in mesh with each said rotatable gear, 15

whereby rotation of said internal gear will adjust said jaws, a handle tube projecting from said shell head, a handle slidable on said tube,

shoulders limiting the sliding movement of said t handle, a spring urging said handle to the limit 20 v of its movement, said handle having a polygonal; shaped portion projecting into said handle tube, said fixed collar in said'shell head having an opening therethrough to admit said portion, said internal gear having a socket opening correspond- 25 ing in shape to said projecting handle portion, whereby, when said openingsare aligned, said handle may be pressed into engagement with said internal gear to adjust the, same and a disk carried by said screws adjacent to and substantiallysealing the'rotatable gears within the internal gear so as to prevent foreign matter from clogging the same. r
